Coherent deglacial changes in western Atlantic Ocean circulation
Abrupt climate changes in the past have been attributed to variations in Atlantic Meridional
Overturning Circulation (AMOC) strength. However, the exact timing and magnitude of past …

Synchronous centennial abrupt events in the ocean and atmosphere during the last deglaciation
Antarctic ice-core data reveal that the atmosphere experienced abrupt centennial increases
in CO2 concentration during the last deglaciation (~ 18 thousand to 11 thousand years ago) …

Barium isotopes reveal role of ocean circulation on barium cycling in the Atlantic
We diagnose the relative influences of local-scale biogeochemical cycling and regional-
scale ocean circulation on Atlantic barium cycling by analysing four new depth profiles of …

Clumped isotope composition of cold-water corals: A role for vital effects?
The carbonate clumped isotope thermometer is a promising tool for determining past ocean
temperatures. It is based on the temperature dependence of rare isotopes 'clum**'into the …

Barium isotopes in cold-water corals
Recent studies have introduced stable Ba isotopes (δ 138/134 Ba) as a novel tracer for
ocean processes. Ba isotopes could potentially provide insight into the oceanic Ba cycle, the …

Ocean mixing and ice-sheet control of seawater 234U/238U during the last deglaciation
Seawater 234U/238U provides global-scale information about continental weathering and is
vital for marine uranium-series geochronology. Existing evidence supports an increase in …

Persistently well-ventilated intermediate-depth ocean through the last deglaciation
Abstract During the last deglaciation (~ 18–11 thousand years ago), existing radiocarbon
(14C) reconstructions of intermediate waters in the mid-to low-latitude oceans show widely …

[HTML][HTML] Reinterpreting radiocarbon records in bamboo corals–New insights from the tropical North Atlantic
Deep-sea bamboo corals (family Isididae) have been used as archives for reconstructing
changes in the past ocean. However, uncertainties remain regarding the interpretation of …

Extended calibration of cold-water coral Ba/Ca using multiple genera and co-located measurements of dissolved barium concentration
Biological productivity and ocean circulation are both important oceanographic variables
that control the distribution of dissolved barium in the ocean interior ([Ba] sw). The ability to …

Investigating the use of 232Th/230Th as a dust proxy using co-located seawater and sediment samples from the low-latitude North Atlantic
The thorium isotope ratio 232 Th/230 Th can be measured in seawater and sediment
samples, and has been used as a proxy to reconstruct lithogenic fluxes to the oceans for the …
